To answer the original question:icon_bigg the only wiring involved as far as harness is extending the TPS wire to the throttle bodys new location. Keep in mind also that most FFI will require relocating the battery in the trunk, so the + cable has to be routed back to the front also and then distributed.
Guys, I cannot begin to explain to you what difference my RonR FFI (long runner) makes. Less lag, better overall throttle response. More air.etc At 19psi on my T04, I went from the -16 settings on my SAFC(stock intake) to having to bring that up in the -5 setting therefore bringing fuel cut back to life:icon_mad: I then had to settle to 17psi. Thats how much more air the engine was seing. I went from a pretty rich A/F at 19psi to being dangerously lean with the new set-up. The clean look and easier spark plugs access is just an extra bonus added. If I'm not mistaking, Duane was one of the few to have the chance to swap intakes and check the numbers, and He gained in the area of 30hp by just swapping the intake. Maybe that also included the bigger TB. I hope he will confirm this.
